RUTLAND — A woman found dead Friday inside a burning house at 2 Joanna Drive has been identified by the district attorney's office as 53-year-old Diane Lamarche-Leader, the woman who lived at that home, and her death has been ruled a homicide.

A 35-year-old homeless man has been arrested in the case, authorities said.

The state medical examiner has ruled the death a homicide. Worcester District Attorney Joseph D. Early Jr. said the cause of death remains under investigation.

Authorities have located a 2004 Toyota Highlander registered to Ms. Lamarche-Leader and reported missing from her home.

Authorities said Amador Roman has been charged with larceny over $250 and receiving stolen property (motor vehicle) in connection with the vehicle. He is to be arraigned Monday in Western Worcester District Court in East Brookfield.

Officials gave no additional information about Mr. Roman's arrest.

The Worcester police log says a man named Amador Yuyo Roman was arrested by state police and booked at Worcester police headquarters about 4:45 a.m. Saturday.

The log book lists a home address for Mr. Roman as 2 Joanna Drive, Rutland, and also refers to him as homeless.

State police detectives assigned to the district attorney's office and Rutland police are continuing the homicide investigation, Mr. Early said.

The house on Joanna Drive where Ms. Lamarche-Leader's body was found Friday morning was boarded up Sunday by workers from M.A. Restoration Inc. of Westboro. Authorities finished investigating at the home Saturday evening.

On Friday morning, police issued a “Be on the Lookout” order for a gray or silver 2004 Toyota Highlander seen in the area. Police said they wanted to question the driver in connection with the fire.

According to records in Worcester Probate and Family Court, Diane Leader-LaMarche and Craig Leader, 50, were married in 1993 and have two children together. Mr. Leader filed for divorce in 2011, and it became final in February of this year.

A woman who answered the door at Mr. Leader's home Sunday evening said the family had no comment. “The children are going through enough,” she said.

Ms. Lamarche-Leader's aunt, Rose Sorel of Worcester, said she last saw her niece at her 82nd birthday party on July 15.

“I loved her dearly, no matter what,” she said, crying on the phone. “My niece invited her — I haven't seen much of her. It was a big party and she brought her son. She was happy-go-lucky. She was a nice person and a good mother who loved her children very much.”

One relative said Ms. Leader was going to move out of the Joanna Drive home the day of the fire.

Firefighters headed to 2 Joanna Drive about 7 a.m. Friday and began battling a three-alarm blaze. The fire was deemed suspicious after it was extinguished.
